Affective computing, as a novel paradigm, adds a new feature into the human-computer interactions era that brings emotions into the process of design and evaluation. Such condition influences digital games’ not only structural dimension but also content and evaluation areas. This study aims to evaluate the effect of using emotions in the form of facial expressions as a User Interface (UI) and the input of a system in virtual scenarios. After studying the findings and methods of previous researches, a conceptual framework for Affective User Interface Design and Evaluation (AFFUIDE) has been proposed. Then, a game in the genre of shoot ‘em up (called Facial Battle) in four interaction modes has been developed. The evaluation of this study has been performed in terms of the players’ performance and experience. For this purpose, 18 male students of the Multimedia Faculty of Tabriz Islamic Art University took part in the experiments, who were asked to play all four modes of the game. Then, after analyzing the normalization of collected data, one-way ANOVA and U Mann Whitney tests were used for the statistical analysis. The findings indicate that the Traditional UI is the most usable and the Full Affective UI has the best sense of fun and user experience among other methods. However, the hybrid mode (affective shooting), is not only usable as traditional mode, but it also works better in terms of user experience compared to other modes.

情感计算作为一种新颖的范例，在人机交互时代增加了一项新功能，将情感带入了设计和评估过程。这种情况不仅影响数字游戏的结构规模，而且影响内容和评估领域。这项研究旨在评估在虚拟场景中使用表情作为用户界面（UI）和系统输入的情感效果。在研究了先前研究的发现和方法之后，提出了一种情感用户界面设计和评估（AFFUIDE）的概念框架。然后，开发了一种以四种交互模式射击游戏的游戏（称为面部战斗）。这项研究的评估是根据球员的表现和经验进行的。以此目的，大不里士伊斯兰艺术大学多媒体学院的18名男学生参加了实验，他们被要求玩所有四种游戏模式。然后，在对收集到的数据进行归一化分析之后，使用单向方差分析和U Mann Whitney检验进行统计分析。调查结果表明，传统UI是最可用的，完全情感UI在其他方法中具有最佳的娱乐感和用户体验。但是，混合模式（情感拍摄）不仅可以用作传统模式，而且与其他模式相比，在用户体验方面也更好。统计分析采用单向方差分析和U Mann Whitney检验。调查结果表明，传统UI是最可用的，完全情感UI在其他方法中具有最佳的娱乐感和用户体验。但是，混合模式（情感拍摄）不仅可以用作传统模式，而且与其他模式相比，在用户体验方面也更好。统计分析采用单向方差分析和U Mann Whitney检验。调查结果表明，传统UI是最可用的，完全情感UI在其他方法中具有最佳的娱乐感和用户体验。但是，混合模式（情感拍摄）不仅可以用作传统模式，而且与其他模式相比，在用户体验方面也更好。
